IMPROVEMENT IN MEASURING AND INDICATING FAUCETS.

Specification forming part of Letters Patent No. 20l,533, dated March 19, 1878; application filed December 31, 1877. i

To all whom it mag concern:

Be it known that we, ANDREW J JOHNSON and CHARLES O. EVARTS, of Cleveland, Ohio, have invented a new and usefullmprovement in Indicating-Faucets, which improvement is fully described in the following specification,

reference being had to the accompanying draw lugs.

The object of our invention'is to indicate automatically, by means of a dial and index connected with the cock of a measuring-faucet, the quantity of liquid drawn through thefaucet, the indicating device being so arranged and inclosedthat the operator cannot tamper with it without detection.

Figure 1 is a front elevation. Fig. 2 is a longitudinal section. Fig. 3is a cross-section. Fig. at represents a part of the indicating device. Fig. 5 is a section of the cock at the dotted line in Fig. 3. Fig. 6 shows parts of the indicating device.

The tube 15 connects the faucet with a vessel from which the liquid is to be drawn. When handle it and cook a are in the positions indi-. cated by dotted lines in Figs. 1 and 2 the liquid flows from tube t through the way win cock at and slot a through the bottom 11 into the measure m. ure m the air escapes through the vent e, the lower side of which is concave. When measure m is nearly filled the spherical float d,

. forated cover, a, to prevent extraneous substances from entering the measure through the vent. The vent 'v is circular, having a lower flange, and is kept in position by band 12 around its'upper end, and which also attaches cover a to the vent. The float (1 may be of cork, hollow rubber, or other suitable material that will float.

The measure m is circular, its lower side projecting slightly under the top of the threaded ring g, so that when ring 9 is screwed on the threaded circumference of bottom b the measure m and its bottom b are held in close contact. The measure is of glass, but may be of any suitable material, and may be removed As the liquid rises in measfor the purpose of cleaning it, by unscrewing ring 9. The bottom I; is attached to and forms a part of box 12 in which cook a turns. 'By turning cock a to the position shown in' Fig. 2, the liquid flows out of measure m through slot a way to, and spout a while float d sinks till it rests on wires f f. The turning of cook 0& (except sufficiently to fill and empty measure m) is arrested by pin 0 Fig. 5, in the side of the cock coming in contact with' the ends of a slot in box 12 This pin at one-end of the box, and the disk '0 and screw 8 at the other end, keep cook a in position. The shaft 6 is keyed in cock a by key a. On this shaft are the cap '0 disk as, and dial d. The cap 0 is loose on shaft 6, and extends over the flange on cock a, and incloses diskw and dial d.

Gap 0 isprevented from sliding on shaft 6 by disk at, keyed to the shaft by key .9, and disk 0 held against the end of the shaft by screw 8. Dial d is loose on shaft e. It hasratchetteeth surrounding it at its circumference on the side contiguous to disk as, and on the opposite side it is marked with index-lines conforming to the spaces between the ratchetteeth. It is turned by a spring-pawl, s, attached to a lug, n, on the interior face of cap 0 and extending through a slot, 00, in disk at. The length of slot 00 exceeds the length of lug n by a little more than the space of a tooth on the dial-ratchet.

When handle h, Fig. 4, is being turned to the right, the cap 0 to which it is attachedor forms a part of, turns loose on its shaft, and pawl 8 turns dial 01 till lug it comes in contact with the end of slot as. Disk :10 being keyed to its shaft, in the meantime remains stationary, and a tooth of the ratchet on dial (1 passes over spring-pawl s, which is attached to disk 00. Then lug n, by pressing against the end of slot 00, turns disk as, dial d,

and cook a till in the position shown by dotted lines in Figs. 1 and 2.-

When handle his being turned to the left to empty measure m, cap 0 turns loose till lug n comes in contact with the end of slot w, as shown in Figs. 4. and 6, the disk as in the meantime remaining stationary, and pawl 3 holding dial d from turning, while spring-pawl s slips .over atooth of the ratchet. Then cap 0 continues to turn, carrying disk 90, dial d, and

, shaft by screw 8 cook a till in the position shown in the drawings. v

The dial d is pressed against spring-pawls s s by contact of its hub with the end of cock a and by the guides 0 0 0 attached to cap a, so that the friction is sufficient to carry the dial with disk 00 and cap 0 Thus, every time measure an is filled and emptied, dial (1 is turned on its shaft the space of one tooth of the ratchet. .The index-wheel is turned on a pin in dial (1 the space of one tooth of the wheel, by contact of the tooth with a slight.

projection on guide 0 at each revolution of dial d on its shaft. The friction of wheel 0 against spring 0 on the pin of the wheel is prevented from turning the spring by a slight groove across the top of spring 0, in which linchpin rests; but when wheel 0 has made nearly a revolution, and pin a in wheel 0 has reached the position shown by dotted lines in Fig. 6, the pin 6 will turn the spring with the wheel, and thus indicate, when the dial is removed'for inspection, that wheel 0 has made a revolution. In the drawings, the teeth of 1 wheel 0 are numbered from 1 to 10 inclusive,

and the index of dial d is divided into sev enty-two spaces, there being a like number of ratchet-teeth on the opposite side.

When dial (1 has been placed in cap 0 in the position shown in Fig. 6, with the projection of guide 0 directly over index-line 72, and between teeth 1 and 10 of index-wheel c, the cap, disk, and dial are placed on shaft 0, and the disk 0 fastened against the end of the A seal may then be placed over the end of disk 0 and the screw, so that the dial cannot be removed from the shaft or tampered with without detection.

tied seventy-two times, dial d will have made one revolution, and wheel 0 will have turned the space of one tooth. When wheel 0 has made one revolution it will be shown by spring 0 having been slightly turned from its former position under the linchpint' by pin e, and will indicate that dial d has made ten revolutions, and that measure m has been emptied seven hundred and twenty times.

To ascertain the quantity of liquid-drawn, the seal over the head of screw 8 may be removed and cap 0 with dial d, taken from shaft 0, and the dial inspected.

There may be as many ratchet-teeth on dial d and as many index-teeth in wheel 0 as may be desirable.

We claim as our invention- 1. A measuring-faucet with the indicatingdial d, having a ratchet, in combination with pawl 8, lug a, cap 0 handle it, and slot 00 in disk 00, connected with faucet-cock a, substantially as described.

2. Ihe cock (0, having the shank or shaft 6, in combination with cap 0 having lug nand pawl 8, disk as having pawl s and slot at, and dial d having a ratchet, all arranged to operate substantially as described.

3. The indeX-wheel 0 in combination with the projection of guide 0, dial d, pawls 8 s disk no, cap 0', and cook 00, substantially as described.

4. The grooved spring 0, in combination with pins i and e, index-Wheel c and rotating dial at, substantially as described.
